Witnesses said they saw the vehicle being driven in a reckless manner at a high rate of speed just before the crash.

The court affidavit said video surveillance from a nearby bar and grill show both teens were drinking there before the accident.

A co-owner of the Waterloo Fire Barn Bar and Grill told KETV NewsWatch 7 the two teens came into the bar to eat Sunday around 4 p.m. Steve Franson said when the teens tried to order alcohol, they were denied.

Franson said the two came back later that night and one of his employees served them into the early hours of Monday morning.

Franson said that server received her certification from the Liquor Control Commission a week ago.

State Liquor Control Commissioner Bob Batt said he didn’t want to comment on the case specifically, but said in general, the Fire Barn Bar and Grill's liquor license could be suspended, cancelled or revoked.

According to an application for a search warrant, investigators said Burke admitted to drinking with Dickmeyer, and a nearly empty bottle of Jagermeister was found at the scene of the crash.

The owner of the vehicle, Amanda Heiman, reportedly told investigators that she served alcohol to Dickmeyer and Burke at the bar just hours before the crash.

The name of the bar was not included in the application for the search warrant.
